WILLILFLIVI THOMAS BUCKINGH'AM EGBERTS, OF LEICESTER, ENGLAND, ASSIGNCR TO U'IIITELD SHOE MACHINERY CUR-PORWEIUN, 0'3 PATERSUN, NEW JERSEY, A COR- PORATION NEW MACHINE FOB, VJURKING UPPEES OVER LAS'ES.

Application filed October 15, 1921. Serial No. 507,900.

To u'ZZ whom it w my concern Be it known that I,,l VILLIAMT THOMAS BUcnrNei-IAM Ronnn'rs, a subject of the King .of England, residing at Leicester, Leicestershire, England, have invented certain Improvements inMachines for VVorL- ing Uppers over Lasts, of which the tollowing description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for w rking uppers over lasts, and is herein illustrated in its application to a machine including in its organization means for pulling the upper over the last and means for lasting the toe ofthe shoe. It will be recog' nized, however, that in many of its features the invention is not limited to machines having both pulling-over means and lasting means. i

IA feature of the invention consistsin anovelorganization comprising upper pulling meanswhereby difiere'nt portions of the upper are pulled at difierent times, the machine herein shown being organized to defer the pulling of the upper at the toe until after it has been pulled at thesides of the forepart and opportunity has been atlorded for adjusting the laterally tensioned upper on the last, for example to straighten the tip seam. In the illustrative machine the margin of theupper is left free about the toe during the. updraw movement of the side grippers, which may have also a foredrawing movement as in prior machines, and is gripped and pulled at the end of the toe at a, later stage of the cycle following a subsequent actuation of the starting means. An important advantage in such a sequence of operations is that it facilitates the adjustment of the upper by the movement of the side grippe s lengthwise of the last and avoids danger of wrinkling the upper be tween the side grippers and the means which grips or clamps the upper about the toe. In the machine illustrated the pulling of the upper at the toe is effected by clamping 'neans which engages the upper continuously round the toe from one side of the toe to the other, the machine including in its organization also means for subsequently lasting the toe of the shoe.

A further feature of the invention conthe upper at the toe in a later stage of the cycle, the machine having also means for operating the wipers subsequently to wipe phe upper inwardly over the bottom of the ast.

The invention also provides a novel organization of pulling-over and lasting means including among its novel features provision for wiping the toe of the upper automatically heightwise of the last, i. e,

for upwiping the upper, by the operation of wipers which are closed into embracing relation to the toe, and provision for controlling themargin of the upper during the upper pulling operation and the overwiping operation of the wipers by clamping pressure which, in the construction shown, is relaxed to facilitate the overwiping of the upper by the advancing and closing of the wipers. Features are also to be recognized 1n novel wiper operating means, the construction shown comprising means for ad .vancing and closing the wipers first yieldingly and then positively together with means for varying the extent of the final positive movement of the wipers.

In another important aspect the invention relates tothe fastening of the upper in lasted position,the machine illustrated having a novel organization of means for applying and fastening a binder to the shoe and for feeding binder material. Among the features included in this part of the invention are novel tacker mechanism and novel means for fastening the ends of a binder to anchor tacks, the construction shown comprising devices which move with the wipers and are operative in a novel manner to drive anchor tacks at the sides of the. toe and to twist the ends of a binder about the tacks. Important. features are also to be recognized in novel means for feeding binder material and in novel means I tor determining the length of the binder,

the machine illustrated having means for Ice determining the length of the feed of the binder material automatically in accordance with the size of the shoe. In the construction shown the binder, wire is fed automatically into a groove in the wipers and the proper length of wire is cut oil at the end of the cycle of operations on a shoe for use in lasting the next shoe, the length of the feed being determined automatically by the size of the wipers with which the machine is equipped.

lhe above and other features of the invention, including certain details 'of construction and combinations of par-ts, will now be "described with reference to the ac companying drawings and pointed out in the claims.

For purposes of illustration the invention is herein shown in its application to a well-lniown type of pullingover machine characteristic features or which are shown and des .:ribcd in detail in various prior bens which car United States Letters Patent, including Patent No. 1,029,387, granted on llune 1t, 1912, upon an application of it. B. Mcl eely, to which reference may be made for a better understanding of details of the organization of the machine not hereinafter particularly described. As in one of the customary forms of this type of machine, the machine herein shown is provided (Fig. 1) with -a sin le pair of side grippers l for each side of the forepart of the shoe, which are operated from the usual cam shaft through updraw levers 3 to pull the upper yielclingly and hold it under tension, and with means including opposite side driver bars 7 for driving at each side of the forepart a pair of upper fastening tacks the rear of the tacks hereinafter re ferred to for fastening the toe binder wire. In the present machine however the usual toe gripper and the front arm with its upper fastening mechanism are omitted to make way for the novel mechanism of the present invention whereby the upper is pulled over the toe and wiped inwardly and fastened in lasted position. Corresponding portions of the frame of prior machaines are also omitted, and in place thereofthe present machine has a frame casting 2 which extends forwardly and cen trally of the machine and substantially parallel to the plane of the bottom of the shoe, this casting having bores extending there through from top to bottom to receive the upper clamping and last depressing members, as illustrated in Fig. 9 and as more particularly hereinafter described. On a forward extension of the frame casting 2 is a guide lfor a wiper head 5 which is mounted to slide lengthwise. of the shoe toward and from the toe of the shoe. To assist in holding thecasting 2 firmly in place -upper and lower plates in planes parallel to the guide and between which are mounted for arcuate swingi" movement memy the wipers and their associated tack driving and binder fastening devices, hereinafter frequently termed for convenience tackers, these members being arranged to swing about a common center at a point substantially coincident with the inner corners of the operative edges of the wipers. Projecting through arcuate 8 located respectively at the opposite extremities of the upper plate 10 of the wiper head are studs 12 through which power is applied to operate the wipers. Each stud projects outwardly from an arcuate plate 14 guided between the upper and lower plates ofthe head and having projecting from its lower face a stud 16 on which is a freeely rotatable pinion l8 meshing with an internal arcuate rack on anieinber 20 which spaces the upper and lower plates of the head and with an external arcuate rack on a carrier for the corresponding wiper and tacker, this carrier also being guided between the plates for arcuate movement. The carriers 22 haveuncunted on their lower faces wipers which project beyond them toward the shoe a sullicient distance to provide an upper flat surface upon which the upper materials round the toe end may be clamped outspread as hereinafter described. Each carrier 22 has also rectilinear guideway 26 extending parallel to the shoe bottom and in thegeneral direction of that end portion of the operative wiper edge which engages the. side of the toe.

Each of the two studs 12 projecting through the upper plate 10 is connected to a link 28 which is guided on a flat surface 3:30 parallel to the wiper head guide and is pivoted to an end of a curved lever 32 the :t'ulcruinof which, midway between its ends, is formed by a stud 34 projecting from the lower face of a bar 36, the upper face of this bar being formed as a rack. The rack bar 86 is guided in the wiper head for move ment lengthwise of the shoe, and carries a spring pressed plunger 38 with a sharpened end seated in a wide V;-notch 40 in the curved lever 32 to maintain the lever normally in a centralized position while permitting the wipers to swing as required to adjust themselves to toes of different shapes.

, The tack driving mechanisms (Figs; 4 to 8) for driving at the opposite sides of the toe the tacks to which the ends of the binder are fastened are carried in tubular casings which are arranged to move into and out of operative position with the wipers. Each casing has near its lower end aprojecting flanged portion 44 constructed to slide into the rectilinear guideway 26 in the wiper carrier Below the projecting portion 44 the tubular casing 42 has formed on it a h ss 46 which receives a screw 48 passing through the wiper 24 and by which the easing is fastened to the wipen Extending from the casing over the wiper is an arm 50 the end of which is confined between the upper face of the wiper carrier 22 and the lower face of the plate it) to assist in steadying the tacker mechanism]. The casing 42 extends upward approximately at right angles to the plane of the wipers and is formed to receive a tack driver guide-52. This guide is cyllndrical and 18 itself bored axially toreceive a driver 54 and a driver bar 56, Un the lower end of the guide are pivotally mounted a pair of oppositely disposed tack holding fingers 58 which are pressed yieldingly toward each other by a spring 60. The lower ends of the two tack fingers, when the fingers are pressed together, form a hemisphere, and one of tie lingers has near its lower end, transverse to the driver passage and parallel to the meeting faces of the fingers, a passage 62 through which the binder wire is fed, as will be hereinafter described. Each of these passages, at that end remote from the adjacent end of the binder wire, is flared, the flare extending approximately to the edge of the tack at the junction of the fingers at the lowest point of the hemisphere.

The upper portion of the guide 52 is threaded,,and the threads mesh with the threads of a screw 64 so that if theguide is rotated it will move lengthwise of the bore in the casing. The screw 64 extends into an nnthreaded hole in the casing 42 which is parallelto the axis of the guide and opens intothe bore of the guide, and is locked in position by a set screw 66. By adjustment of the screw 64 upwardly or downwardly the position of the guide may be varied in order to locate the passage 62 in the correct position to receive the binder wire. 7

For rotating the guide 52 to twist the end of the wire about the tack, the guide has formed upon it a peripheral series of gear teeth which mesh with a gear 68 fast on the lower end of a shaft 70 rotatably mounted in a projecting portion of the easing 42 in parallel relation to the guide 52. Each shaft 70 in driven by means of a flexible shaft 72 at the time when the upper has been wiped over the edge of the last bottom and the tacks have been driven, the guide thus being turned and at the same time elevated by its threaded connection with the screw 64 to twist the end of the wire about the partially driven tack and to raise the tack lingers finally above the head of the tack and to free them from the wire which slips through the passage 62 as the fingers are rotated and raised.

The driver bar guide 52 has at its lower end a relatively small bore l4in which the driver 54 is guided, and at a short distance from the lower end of the guide this bore is enlarged to receive the driver bar 56 and a lifting spring 76 which bears upwardly against a shoulder on the lower end of the bar 56. The upper end portion of the driver 54 is received in a bore in the bar 56 and is seated against a screw plug 78, the driver being secured in place by means of clamping screws 80. On the upper end of the bar 56 is adjustably threaded a cap 81; The tack is discharged into the tack pocket formed by the fingers 58' from a duct 82 formed in the guide52 and the casing 42, the tacks being fed through a flexible tack tube connected to the usual separator mechanism. v

In order to assist further in steadying the wiper and tacker mechanism, each casing 12 has an arm which extends in substantially parallel relation to the wiper plane and as the wipers close in passes over a sui' lace formed on a portion off the name, this arm being useful in resisting the downward thrust which occurs luring the stretching of the upper as hereinafter described.

It will be understood that the wipers are secured directly to their carriers by suitable means which permits them to be readily detached when different wipers are to be substituted, such connecting means being sup plemented by the connections through the tackers which are mounted in the rectilinear guideways 26, as hereinbetore explained. As shown in Fi x 3, the wipers when fully opened abut along a line extending lengthwise of the shoe, and the point where the operative edges of the wipers meet is displaced but little forwardly of a line connecting the opposite extremities of these edges. The wiper edges have formed in them a continuous groove 88 in which the binder wire lies during the operation of the wipers. Different wipers are provided for different styles and sizes of shoes, and the rectilinear guideways 20 are so disposed in relation to the operative edges of the various wipers that the taekers will be correctly located in positions to be secured to the different wipers, whatever wipers are used.

The upper clamping plunger 90 has a curved foot 92 (Figs. 9 and 10) to clamp the margin of the upper materials fiat upon the upper surface of the wipers when the latter are advanced and closed in to embrace the toe of the shoe. The last depressing plunger 94: has a foot 96 with three triangularly spaced surfaces to engage the sole or insole on the bottom of the last near the toe end. The plunger 90 has a transverse swivel pin 98 through which passes an operating rod 100 having fast thereon collars 102 and 10st at opposite sides of the pin, a spring 106 being confined between the pin and the upper collar 10.2. The last depressing plung or 9st is made in two parts threaded one into the other to permit adjustment of the position to which the last is depressed by adjustment of the length of the plunger. The upper end of the plunger operating rod 100 is pivoted to one corner of a triangular plate 108another corner of which is pivoted to one of the lower corners of a second triangular plate 110, the other lower corner of the latter being pivoted to the top of the last depressing member 91 The second triangular plate 110 is pivoted (Fig. 1) to one arm of a bell crank lever 112 which is pivoted on the frame of the machineand the other arm of which is connected by a link 114 to the front end of a lever 116 corresponding to the lever hertofore used in machines of the M'eFeel'y type for operating the toe gripper. The rear end of this lever in the present machine is positively connected to the usual toe gripper operating cam slide by means of a link 118.

When the plate 110 is depressed by the upward movement of the front end of the lever 116, the foot 96 and the curved foot 92 are moved downwardly to engage respectively the sole or insole and the margin of the upper outspread over the wipers and by continued movement clamp the upper upon he wipers and positively depress the last to pull and stretch the upl er about the toe of the last. In this operation the margin of the upper is yieldingly clamped through compression of the spring 106, and as the last is depressed the upper is permitted to slip between the clamp member and the wipers as required in response to excess of tension at different points. The triangular plate 108 is at this time prevented. from turning by means of alingcr 120 the rear end of which is in engagement with the front end or the usual rack bar member 122 which in this type of machine controls the closing in and spreading apart of the grippers and tackers. ll hen this rack bar member retires to permit inward movement of the sic e grippers and tackers, the plate 108 is permitted to swing about its pivotal connection with the plate 110 till the collar 10 1 engages the pin 98, thus relieving the margin or the upper of the pressure applied by the spring 106. Connected however to an arm of the finger 120 is a lighter spring 124 which at its front end is connected to a hook 126 (Fig. 1) passing through a pin 128 mounted in the frame member 6, the hook being adjustable by means of a nut 130. By its connection through the finger 120 to the upper corner or the plate 108 the spring 12a thus applies a yielding downward pressure to the plunger rod 100, causing the foot 92 to continue to hold the margin of the upper yieldingly for the ov'eru iping operation but under less pressure than applied by compression of the spring 106' in the upper pulling operation.

The rack bar 36, to which the wipers are connected hereinbetore explained, is operated by a gear segment 132 (Fig. 1) which is'pivoted on the frame casting 2. This segment is operated by a link 134 pivoted to an arm 136 last on a transverse shaft 138, this shaft having fast thereon a gear segment 140 connected to the upper end of a vertical raclr bar 1 12. The lower end of this rack bar is engaged by a second gear segment 144 formed on one arm of a bell crank lever 1 56' which is pivoted on, the frame and the other arm of which carries a swivel pin 1 18. Throughthe pin l l ilpa-sses an operating rod the front end of which is connected at to the usual heel rest operating lill) crank lever 146.

i the shaft 138 is a lever 168 one arm of which carries spring pressed pivoted pawls 170 adapted in certain relative positions of the arm 164 and the lever 168 to engage the ment over the bottom of the last. The pawls 170 have cam shaped tails172 arranged to engage a pin 17 4 which in certain positions of the lever168 raises the pawls from the teeth. This lever 168 has a second short arm 17 6 formed as a gear segment meshing with a second segment 17 8 formed 011 one arm of a lever 1'80 pivoted on the frame. The other arm of the lever 180 carries a cam roll 182 mounted on an eccentric stud 184, this roll being arranged to engage a cam 186 formed on a plate secured to the rocking lever 188 by which in this type of machine the rack bar 122 and associated parts are operated to cause the inward swinging move ment of the grippers and tackers as hereinbefore explained.

It will be understood that it is by the movement of the lever 188 at the time when the side grippers and tackers are swung inwardly that the lever 168 is operated to im part through the pawl and ratchet device 170, 166 the final operative movement to the wiper operating connections. The eccentric stud 184 has on its end an arm 190 carrying a spring pressed plunger by the engagement of which with one of a series of holes 192 in an arc member 194 on the arm 180 the roll 182 may be held in different adjusted positions, thereby controlling through engageinent of the roll with the cam .186 the initial position ofthe lever 168 and of the pawls 170 and their tails 172 in relation to the pin 174. This serves to determine the point in the stroke of the lever 168 when the pawls will come into operative engagement with the ratchet teeth on the arm'164 and thus to detern'iine the extent of movement imparted, by this mechanism to the wipers. i i

' Each pinion 68 which rotates the driver bar guide 52 is connected by a flexible shaft 72 to a beveled pinion 196 (Fig. 1) on a short shaft 198 mounted in hearings in the frame, this pinion being rotated by a gear segi'nent 200 fast one second shaft 202. East on the shaft 202 is also a pinion 204 engaging a rack bar 206 on the upper end of a rod 208 which at its lower end has a roll 210 riding on a cam 212 fast on a counter-shaft 214 which is driven by the main cam shaft through a pinion connection. This cam has a gradualrise for imparting the turning movement to the guides 52 to twist the wire about the tacks and a quick drop to return the parts to normal position. The roll 210 may, if desired, be held to its am by a suitable spring (not shown).

Each driver 54 is operated against the resistance ofits spring 7 6 by a lateral extension member 216 (Fig. 1) on the nearest side driver bar, this member engaging the cap 81 on the top of the member 56 to force the latter downwardly. The extension 216 is pivoted on the side driver bar to swing about an axis parallel to the bar and is held initially in an outwardly swung position by suitable spring and stop mechanism 217, 219, the extension having on its lower end a lug offset inwardly and engaged by the cap 81 on the member 56 as the wipers and their tackers are swung inwardly, each tacker thus picking up its operating member 216 and carrying it inwardly into tacking position. This arrangement renders the operat ing means adaptable to different positions of the wipers and tackers as required for different styles and sizes of shoes.

The wire is fed to the groove 88 in the wipers 24 through the passage 62 in the tack finger of one of the tackers and into the passage in the other tacker by automatic feed mechanism which is omitted from the general view (Fig. 1) but is shown in detail in Figs. 11, 12 and 13. By reference to Fig. 1 it will be noted that the frame casting 2 has slideways 218 extending inwardly toward the position occupied by one of the tackers on the wipers in a plane substantially parallel to the wiper plane. Slidingly mounted in these guideways is a frame 220 (Figs. 11 and 12) having in it bearings for various operating shafts and plungers. One of the shafts 222, has frictionally connected to it a pinion 224 which engages a rack 226 slidingly mounted in a guideway 228 in the frame member 2 and limited in its sliding movement by stops 230 and 232. On the same shaft 222 is a second pinion 234 which is fast on the shaft and engages a pinion 236 on a second shaft 238. The shaft 288 at its upper end is threaded into its hearing, and the pinion 236 has a splined connection 240 with the shaft, permitting the shaft to move lengthwise through the pinion.

The lower end of the shaft 238 has teeth 242 tically in relation to the shaft 248 which it drives. The position of the plunger 246 is controlled by a spring 250, which urges it upwardly, and by a cam roll 252 which is guided for vertical movement and has a stud engaging in a peripheral groove in the plunger. The roll 252 is arranged to engage a cam surface 254C against which it is held by the pressure of the spring 250, this cam surface extending along a portion of the frame plunger 263. The throat 25 8may have any well-known clutch device to prevent, reverse feed, oruie'wirg The wire issuppli'ed from a'ijeel 2,62 carried by the frame 220 and it is severed at the outlet end of the throat, 258 byfthe shearing cut of a nicked rotary cut ter 264; through the niel: in which the wire isfedj This'cutter is fasten the end of a shaft 266fin thesaine plane as the throat but inclined. to the throat and having at its outer end an armyszssjbv which the shaft may be rockedv to sever the wire either manually or by the' aetion on the arm ofa plunger 270. This plunger is operated at the end, ofthe wire feed by means of a cam 272011 a pinion wliichi sfast. on the driving shaft 276' and engages the pinion 23% on the shaft. 22'

The feedlng andsevering of the wire takes place as the machine coines'to a stop after,

completing 'its cycle of operations on the shoe, the n iechanisni f o rdrivingthe shaft 275 of thewire ii'e'edingun ea ns being operated, and controlled utomatically byniechanisni hereinafter "described to turn the shaft firstinone direction and thenin the reverse direction. As the shaft. 276 begins to turn it drivesthe shaft. 222 and the shaft'238, and alsodrives"frictionally the pinion 22awhich engages the rack 226 This pinion first slides the raclroutwardly to its 7 movement determined by the stop 232Vand then by continued moven'ient acts to "force he frame 220 and its supported mocha-n an inwardly along the guideways 218 until the frame engages the tacker mounted on the wiper on that side of the machine, where upon, the pinion 2 24s-ceases; to rotate. In

the meantimejtheshaft SS is turned the pinion 236 with a downward novemen t due tothe action of its threaded upper end on the threadedbearing, such dow nward moveinent of the shaft continuing as long as the driving shaft 276 continues to rotate in the initial: direction. the timewhen theteeth24l-2 of the shaft-23S limit of It will be evid-ent'that engage the teeth an of the wire feed plunger 246 depends upon the vertical position of this plunger which is determined by the action of the cam face 25% on the roll 252, and furthermore that the position of this roll, detern'iined by the cam face, depends upon how far the frame 220 has been moved inwardly efore being stopped by the tacker. It will also be evident that the extent of inward movement of the frame will be different for different sets of wipers, the frame moving. farther inward ly when the machine isequipped with wipers for operating on a small size shoe than when wipers are used for operating on a larger shoe because the tacker is positioned farther inwardly. The extent of the effective feeding movement of the wire feed plunger 246 and its shaft 2&8 in proportion to the uniform movement of the driving shaft 276 is thus regulated automatically to feed the correct length of wire required for different sizes of shoes.

It will be understood that when the shaft- 238 becomes clutched to the plunger 2&6 feeding movement is imparted to the wire feed roll 256 and continues until the shaft 276 ceases to turn in the initial direction. The wire passes into the opening 62 in the nearer t acker this opening being directly in line with the throat 258, and then along the smooth sweep of the wiper groove 88 and into the opening in the other tacker. As the driving shaft 276 comes to the end of its movement the cam 27 2 meets the upper end 286. of the plunger 270, which is pivoted on the main part of the plunger and is normally held by a spring in alignment therewitln andturns the end of the plunger about its pivot without depressing the plunger. The shaft then reverses its movement, and while the lost motion between the rack 226 and the stop 230 is being taken up, the cam 2?;2 depresses the plunger 270 to effect the cutting of the wire. As the parts thus reversetheirmovements, the ratchet teeth 242 are permitted to slip over the ratchet teeth 24ft until theshaft 238 has been turned upwardly to disenga 'ethe teeth. lVhen the shaft 276 arrives at the end of its reverse movment the shaft 238. is returned to its initial upper position and the frame 220 is moved outwardly to its initial position to afford room for the subsequent operation of thewipers on another shoe.

The required movements may be imparted to the shaft 276 by any suitable mechanism, the construction illustrated comprising a constantly running electric motor 290 arranged to drive the shaft in its reverse directions through clutch controlled reversing gear mechanism shown in Fig, 1. The shaft 27eis conneetedby flexible shafting 292 to a short shaft 294thaving thereon a beveled pinioir296 in engagement with a gear segment 298 loosely mounted on the shaft 202 and having fast thereon a pinion 300 which is operatively engaged with a gear segment 302 on the end of a lever arm 304: pivotally mounted on the frame. The arm has a slot in which is mounted apin 8G6 carriedby a disk 308 which is fast with a pinion 310, the latter having operative engagement with aworm 312 fast on a shaft 314. Splined on the shaft 31% is a clutch member 316 which is arranged to engage a co-operating memher 318 on the shaft of the motor 290. For :ontrolling the clutch member 316 a pivoted bar 320 is provided which is connected with the clutch member and has at its .upper end an offset lug 322arranged normally to eX- tend into a notch in a controlling disk 324 which is fast with the pinion 310. On one side of the bar 320 is a projection 326 which is arranged to be engaged by a spring plunger .328 mounted in the outer end of the lever arm 136 through which movement is imparted to the wiper operating link 13%. As this lever arm returns to its initial position just before the machine comes to a stop, the spring plunger 328 engages the side of the lug 326 and swings the bar 820 rearwardly against the resistance of a spring 330, withdrawing the lug 322 from the notch in the diskBQ i and at the same time carrying the clutch member 316 into engagement with the member 318. The motor is then effective to turn the pinion 310 and the connections to the shaft 276 and continues to do so until the pinion. has completed a revolution, the pin and slot connection to the lever arm 30% acting to swing this arm first in one direction and then in the reverse direction for imparting similar reverse movements to the egment 298. It will be understood that the spring plunger 328 slips past the lug 3536 on the bar 320 and immediately releases the bar, thus permitting the lug 322 again to enter the notch in the controlling disk to disconnect the clutch when the pinion 2510 has completed a revolution. When the arm 136 receives its wiper operating inoveinent the spring plunger 328 yields without effect upon the member 326 which it engages.

In the operation of the machine, the operator presents the shoe with the sole or in sole in engagement with the shoe rest 278 which in the present machine is arranged to engage the shoe farther rearwardly than is usual and has a rounded shoe engaging surface. Forwardlyof the shoe rest the sole engages the last depressing member 96, and the toe end of the last is presented in engagement with the concave inner surface of the foot 92. The margin of the upper is positioned in the open side grippers, and its toe portion is outspread under the foot 92, the wipers at this time being retracted fromthe shoe. The machine is then started,

and the main cam shaft makes a partial revolution and then comes automatically to rest. In this stage of the cycle the side grippers grip and pull the upper across the forepart of the last with a force deter-- mined by adjustment of the usual updraw springs, and preferably give it also a foredrawing stretch as common heretofore in many machines of the illustrated type, the heel rest 280 in the meantime being moved forward into yielding engagement with the shoe by the operation of the cam slide 161. By the operation of the segment 132 through its yielding connection with this cam slide forward movement is at the same time im parted to the rack bar 36 and to the arcuate slides let, the friction between these slides and the wiper head, which may be increased by any well-knownfimeans if found desir able, causing thewiper head first to be advanced bodily toward the shoe before the wipers begin to close. Theforward movement of the wiper head is arrested, when the wipers have been advanced substantially to the end of the toe, by the engagement of a yielding plunger 282 (Fig. 2) on the wiper head with a portion of the frame of the ma chine. The continued movement of the rack bar86 then causes the wipers to close about the toe of the shoe through the rack and pinion connections 18 and 20, the closing movement of the wipers continuing until the tackers which they carry engage the sides of the toe of the shoe, the position of the wiper-satthis time being somewhat below the plane of the shoe bottom. Further movement of the wiper operating connectionsis then takenup by the yield of one of the springs 162. It will be understood that in' this preliminary movement of the wiper operating means the lever arm 164: is swung rearwardly to carry its ratchet teeth into position to be engaged subsequently by the pawls 170.

lVhile the machine is at rest with the wipers thus positioned the operator is en abled to make any of the usual adjustments, for example to straighten the tip by relative movement of the side grippers, the toe portion of the upper being still free to permit the tip straightening or other adjustment of the upperto be effected without any tendency to twist or wrinkle the upper about the toe.

Upon the subseqijient starting of the machine the lever 116 receives its operative movement, thereby clamping the'margin of the upper outspread upon the wipers by the action of the foot 92'a1id forcing the toe end of the last downwardly by the action of the member 96, the upper being thus pulled and stretched and also wiped tight ly and smoothly over the last and close to the sides of the last round the toe end,' its margin being permitted to slip and give up: stock at different as under yielding: control of; the foot In its depression the last rocks somewhat. about the rounded sole rest 278, and in: or der to permit such rocking movement. the heel rest 2.80 of the present machine is not. locked until a later time in the cycle than in prior machin s. The-- depression of. the last continues until the margin of the sole or insole is positioned slightly below the levelor" the wipers, and: the usual side clamp arms 2-79 are then swung inwardly intoposition to support the shoe for. the ovorwiping and tacking operations.

As soon as the; last has been pressed below the wipers, the wipers and: their tackers are released by the shoe and: that, one 015- the:

springs 162 which. was compressed by the: excess movement. oi the wiper operating means. is then permitted to act to advance:

and close thewipers over the shoebottom, the springplunger; 282: yielding to permit the advancing-movement. At this time, by the retractive movementof the; member 122 and its connections, the side grippers. are permitted to move inwardly. andthe. side tackers and their wipers also are moved. in-

wardly tooverlay the upper as usual at thesides of theforepart, the side tack; driver bars T being finally tripped to causethem to drive the side tacks. The rearward movement of tlie meinbe-r 122,.byitscontr0l of thefinger 120, causes the-clamp.- member 92 to relax its pressure on the margin of the upper, as hereinbefore. explained, to permit the marginto slip morefreely under control of the spring 12%. in the overwiping operation. The advancing and closing. movement of the wipers is completed positively through the pawland ratchet device 1.7 O, 166. operated: as hereinbeforei explained by the movement of the lever 188 whereby the retractive movement; of the member. 122. is eff cted. The side tack driver. barsare not tripped until the wipers have completed their advancing and closingmovements, the caps 81 on the toe tackers being then positioned under the operating members. 216 on the driver bars, and when. these bars are operatedrthe tacks at the sides of'the toe for iiasteningthe binder are driven simultane ously with the other tacks. The mechanism for rotating the driven bar. guides 52; then begins to act, and the tack fingers byatheii: rotative movements serve to tighten the wire round. the toe and then to twist its ends about the partially driven tacks. Theguides 52 rotate in opposite directions, and

theflared ends of the passages 62;first move. toward each other and toward the heel end of the. shoe to tighten the wire, the continued rotationwof the guides and their coincident upward movement serving. to twist he tightenedwire several times. roundthe tacks, stripping the wire first graduallysages, the tack fingers being raised above the heads of the tacks. The various parts of the machine are then returned to their starting positions, the tack fingers moving outwardly to clear the tacks before they are again screwed downward. Just before the machine comes to a stop the wire feeding nechanism is started in operation by the action of the spring plunger 328 on the controlling. bar 320, and the wire is fed into the wipers and tackers and cut off to leave a: toe binder in place ready for the operation upon the next shoe.
